苎麻良种繁育过去多采用种根繁殖,种根繁殖经历了从大种根繁殖到小种根繁殖,再发展到细切种根繁殖的演变过程。繁殖系数由小到大。用种根繁殖,对于保持良种种性和纯度,增加无性繁殖系数,扩大良种栽培面积,虽已起着积极的作用,但此类繁殖方法必须在挖取麻蔸的基础上进行,而且繁殖系数也不理想,所以,在育种上应用有一定的局限性。 In the past, ramie breeding breeding use of multi-species breeding, seed multiplication has experienced from the breeding of large seedlings to small seed multiplication, and then to the development of fine-cut seedling evolution. Breeding coefficient from small to large. Breeding with the kind of root, for maintaining good breed sex and purity, increase asexual reproduction coefficient, expand the cultivated area, although it has played a positive role, but such breeding methods must be based on digging mound, and the breeding coefficient Not ideal, so, there are some limitations in the application of breeding.
